GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 789,323, dated May 9, 1905. Application filed December 8, 1904:. Serial No. 236,063.

To all whom it may concern:

Be it known that I, FRANK C. HoneKIss, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of Calii ornia, have invented certain new and useful Improvements in Gas Governors, of which the 'following is a specification.

My invention relates to improvements in gas-governors.

The objects of my invention are to provide a gas-governor to keep gas as used for heating and lighting at such pressure as may be desired and in which the blowing of gas at the orifices intended for its escapeis prevented therebypreventing the waste of the same and also by certain novel features so far as relating to gas-governors to expedite the inspection. of the interior of the device or its dismemberment.

My invention consists in the novel construction and arrangement of parts, which are hereinafterldescribed, illustrated in the accompanying drawings, and claimed in the appended claim.

In the drawings, Figure 1 represents a longitudinal section of my gas-governor, and Fig. 2 represents a detail view of the aperture for the escape of air in the cover thereof.

In the saidfigures, 1 represents the pipe running from a gas-meter and screwed into the lower casing 2 of the governor from which the pipe 3 leads to the different jets of the gas system. I

4 shows the upper casing, having a lower compartment inclosed by easing 2, having an annular recess 5 for holding quicksilver and upon which rests the cap or flanged cover 6, through which runs the rod 8, which is secured by means of the nut 9. To the lower and threaded end of the rod 8 is secured, by means of nut 11, the semicircular valve 10, adapted to contact with the sharp annular edge of the bushing 13. The cap 14 is so threaded that it may be screwed into the lower compartment 2 when the upper one containing the valve has been removed for repairs, so that the supply of gas need not be discontinued. In the under side of the cover 14 is the threaded flange 17, wherein is the slot or opening 16, and said cover 14; has the lugs 15 for the purpose of facilitating the removal of said cap.

The side lugs shown at the center of the device in Fig. 1 facilitate the removal of the reservoir from the casing.

In the operation of the device gas enteringby means of the pipe I penetrates the interior oi valve 10,i'orcing it upward toward the lower interior edge of bushing 13, the weight 7,1'esting on the cover 6, being of such heaviness as to prevent the entire closing of the aperture, as shown, in bushing 13 and yet to allow of the entrance of" a sufficient quantity of gas for lighting or heating purposes, so as to maintain an even pressure without the result of intermittent pressure or blowing of gas. The quicksilver to remain in recess 5 prevents the escape of gas at this point,which will ind entrance upwardly from the reservoir where rod 8 penetrates the top of compartment 4. The slot or opening 16 prevents the compres sion of air when the cap 14 is screwed down. Should the pressure of gas in valve 10 be su'f iicient to close the opening at point 13, the burning of the contents of the compartment will cause a lowering of the valve on account of the absence of upward pressure of gas from the compartment, thereby admitting more gas to the compartment, and thus keeping up the supply of gas to the system, the said lower comp artinent having a central lug on its top penetrated. by red 8, which prevents the vibration of the rod 8. The bushing 13 is raised above the base of said lower co1npart ment, so as to prevent the settlement of a great amount of oil contained in gas above the valve, so as to prevent its operation, the same resting in the receptacle formed by the inward-projecting wall of the bushing and the walls of said compartment. The said valve is ball-shaped to prevent sticking.

Having thus described my invention, what I I claim as new, and desire to secure by Letters l Patent, is-

In a gas-governor the combination of a bottom reservoir for gas having central longitudlnal openmgs and a side aperture and an inward-projecting bushing at its base, a lower casing, substantially as shown and de 10 movable rod to move through said openings scribed. sustaining a valve at its lower end, an inner In testimony whereof I affix my'signature cap for said esergoir, means for preventing in presence of two witnesses.
